Title: Direct measurement of astrophysically important resonances in K 38 ( p , γ ) Ca 39

Abstract

Classical novae are cataclysmic nuclear explosions occurring when a white dwarf in a binary system accretes hydrogen-rich material from its companion star. Novae are partially responsible for the galactic synthesis of a variety of nuclides up to the calcium (A ~ 40) region of the nuclear chart. Although the structure and dynamics of novae are thought to be relatively well understood, the predicted abundances of elements near the nucleosynthesis endpoint, in particular Ar and Ca, appear to sometimes be in disagreement with astronomical observations of the spectra of nova ejecta.

Figures / Tables:

FIG. 1 FIG. 1: (a) Sample rate vs. time curves measured in the NaI detector. The green filled circles correspond to a run where the beam rate was constant, while the blue filled squares correspond to a run where there were significant changes in the rate. The solid orange lines show themore » fit results used to extract the average beam intensities. (b) Average beam rate determined for each ∼1 hour run taken during the experiment. The filled circles, rectangles, and triangles denote each run’s beam energy, as indicated in the legend.« less
